TestRX Research Breakdown

Basically, this supplement consists of ZMA, a few vitamins, Fenugreek, and D-aspartic acid.

The biggest problem we see with the ingredients is that the doses in TestRX are much less than the doses used in research.

Fenugreek:

Testosterone Boosting Evidence: Weak evidence

Let’s get fenugreek out of the way first. At least half the testosterone boosters we analyze contain Fenugreek, but the research on it is inconclusive. More studies than not show it’s ineffective (3, 4). The TestRX website cites this study (3) as evidence toward Fenugreek being a testosterone booster. However, there are some problems with their logic. First, if 600mg was the amount used in the study, why does TestRX only include 75mg? Second, even though the subjects’ libidos increased, their testosterone levels didn’t change. In another study cited on TestRX.com, there was a small increase in testosterone levels, but the researchers used 500mg per day (5). Again, this is much higher than TestRX’s 75mg.

D-Aspartic Acid:

Testosterone Boosting Evidence: Plausible

The research on D-aspartic acid looks more promising than the research on Fenugreek. It’s one of the two forms of the amino acid aspartic acid. Aspartic acid plays a role in regulating testosterone. One study looking at 3g of D-aspartic acid supplementation per day found a 42% boost in testosterone by the end of the study (6). Another study found that 2.66g of D-aspartic acid increased testosterone in infertile men by 30-60% over 90 days (7). The only study looking at D-aspartic acid’s effects on resistance trained men found no change in testosterone levels (8). Unfortunately, TestRX only includes 0.575g, much less than the researched dose.

ZMA (Magnesium, Zinc, & Vitamin B6):

Testosterone Boosting Evidence: Plausible

Research shows ZMA has the potential to improve testosterone levels in athletes. ZMA’s benefits come mostly from zinc. There’s no stand-alone research on vitamin B6 or Magnesium to show that they have testosterone boosting benefits. One research study found that 30mg of a zinc-magnesium supplementation daily increased testosterone in football players (9). Another study found that zinc supplementation improved testosterone levels in male wrestlers (10).

Vitamin D3:

Testosterone Boosting Evidence: More research needed

Limited research on vitamin D3 shows that it may have benefits as a testosterone booster (11).

Vitamin K:

Testosterone Boosting Evidence: No evidence

Research on vitamin K shows that vitamin K deficiency may lead to testosterone deficiency (12). Research doesn’t back it as a testosterone booster at this time.

TestRX Reviews

This product only has two reviews listed on their Amazon page.

Assuming, that they are both legitimate reviews, they are rather mediocre.

Max reported no benefit.

Antonio said TestRX were great but didn’t explain why he didn’t leave a 5-star review.

TestRX Pros and Cons

There aren’t many reviews available on TestRX, and the research is mixed.

Is it worth trying?

Here are some reasons you may want to buy it.

Pros

Leading Edge Health offers a 60-day money-back guarantee

The company breaks down the dosages of each ingredient.

Cons

Expensive (about $2 per day)

Lack of customer reviews on Amazon

TestRX Bottom Line

So what’s the bottom line on TestRX?

Is it worth your money?

Unfortunately, we’re going to have to give this testosterone booster a pass.

It actually contains a solid ingredient list, but the doses are too low to have a significant benefit for you.

We don’t want you spending $60 on a supplement per month unless there’s substantial evidence that it will improve your workouts.

TestRX lacks that evidence.

If this product were selling for half the price and contained twice the dosages, it would capture our attention.

However, after breaking down this testosterone booster, it seems like the company was cutting corners to save money.

We recommend that you try a testosterone booster with more customer reviews to back it.
